HERBERT E. DUNLAP, or W HEELING, WEST VIRGINIA..

BEMOVABLE-HEAD STEEL BARREL.

Application filed April 17, 1917.

To all whom t may concern:

Be it known that, I, Hnnna'r E. DUNLAP, a citizen of the United States of America, and resident of Vheeling, county of Ohio, and State of W'est Virginia, have invented certain new and useful Improvements in Removable-Head Steel Barrels, of which the following is a specification.

This invention relates broadly to sheet metal receptacles, and more particularly to metallic barrels or similar containers.

The primary object of the invention is to provide a steel barrel or like container having a head which may be readily inserted and removed as occasion requires and which is not only securely retained against chance displacement but also maintained in Huid tight relation to the body of the container'.

A still further object is to provide a. metallic barrel of the removable-head type having its edge reinforced by a relatively heavy ring or chime disposed in embracing or inclosing relation thereto whereby said edge is etfeetually protected against injury from rough or careless handling.

A still further object within the conemplation of the invention is to provi e a flanged removable barrel head having means associated therewith whereby downward seating pressure is applied to said head simultaneously with the expansion of its flange into close-fitting relation to the barrel body.

With these and other important objects in view, the invention resides in the features of construction. arrangement, of parts and combinations of elements which will hereinafter be exemplified, reference being had to the accompanying drawings, in which-d Figure 1 is a detail sectional view of the invention;

Figs. 2 and 3 are similar views illustrating slightly modiied forms of locking rings;

Fig. 4 is a similar view showing a modified form of chime and a locking ring therefor; I

Fig. 5 is a view similar to Fig. 1 illustrating in full lines the initial or entering position of the locking ring and in dotted lines the final or seated position o'f said ring; and# Fig. 6 is a top plan View of a portion of the locking ring, illustrating expanding means therefor.

Referring to said drawings, in which like Specification of Letters Patent.

designating characters distinguish like parts throughout the several views- 1 indicates generally the body of a steel barrel which is flared outward adjacent to its upper end to forni an offset marginal edge or rim 2 whereby an external annular shoulder 3 and an internal annular shoulder 1 are provided. Disposed in exteriorly embracing relation to said rim or margin is a chime 5 of relatively heavier material and which is preferably of substantially even thickness throughout, said chime having its lower edge 6 inturned to conformably seat in underlying relation to said external shoulder and having its opposite edge 7 flanged over the edge of said rim and disposed interiorly of the latter, but terminating at a suitably spaced distance from the internal shoulder 4, thereby forming an intermediate internal channel 8.

A seat for a removable barrel head 9 is provided interiorly of the barrel at a suit,- able distance below the flare or offset by which said shoulders are formed, said seat. being preferably constituted by an inwardly pressed rib 10. Said head 9 has an upright peripheral flange 11 which. in the seated position of said head, is adapted to closely nest against or engage that portion of the barrel located between said offset and the seat 10, the thickness of the chime and the extent of the offset being relatively proportioned, as will be noted, to permit of unobstructed introduction and removal of said head past said chime-that is to say. the offset is sufficiently greater in extent than the thickness of the inturned upper edge 7 that ready insertion and removal of the head is permitted.

i n open steel expansion rin 12 is designed for mounting in seated c amping relation to the head 9 and for locking said head in position. Said ring preferably has a vertical width. or height, equal to or slightly greater than the distance between the shoulder constituted by the terminus of the chime fiange 7 and the upper surface of the body of the head 9 when the latter occupies seated position. The body of said ring is of substanti lly flat band-like form and has a circumferential projectin rib 14. at or adjacent to its upper edge, whic ,when said ring is expanded, projects into the channel 8 and interloeks withV the superjacent chime flange or shoulder 7.

Said rib, or at least the superfrontal portion thereof, is of inclined or at 15, and, when said ring is being expanded, said portion is presented Ato the adjacent 5 nose-like edge or angle of said chime flange.

Consequently, as said ring is expanded against said chime flange the said angle rides upon said inclined or curved surface of the ring and servesA to force said ring downward for depressing the head 9 to seating position, the lower edge of said ring beiu seated upon said head, as shown. In ot er words, expandin force applied to the -ring causes the flat bo y portion of the latter to be forced into pressure-exerting relation to the head-flange-ll' and the rib 14. to enter thevchannel 8; and, as said ring is expanded from its initialor entering position, shown in full lines in Fig. 5, to the final or seated position indicated in dotted lines in said figure, a drawing or wedging force is exerted through the lnterengaging surfaces of the rib 14 and the chime ange 7-for depressing the ring and the subjacent head 9. While the said chime flange mlght obviously be formed to present an'lnclined or beveled face to the inclined or curved surface of the rib, I prefer that it present the sharp edge or angle shown in the drawings, thereby to reduce to a minimum the frictional resistance offered by said engaging parts to expanding movement of the ring.

The outer surface of the expansion ring is preferably shaped to conform as nearly as is practicable to the surfaces to be engaged thereby, as, for instance, the ring disclosed in Figs. 1, 2 and 5 has the under surface of the integral rib adapted for seating upon the shoulder 4 when its body portion is closely seated against the head-ange 11; or, when it is desired to dispose pressible material in a position for sealing the joint between said'llange and the barrel body, as shown in Fig. 3, the. rib 14a is so proportioned and shapedv that, in the final seated position of said ring, it occupies'overlyin compressing relation t'sa'ld gasket. In tge modification shown in Fig. 2 the head flange is formed. with a terminal bead 16 and the ring 12b has an external annular groove orehannel 17 formed therein for the recep- ,tion of said bead.

In the modified form of the invention disclosed in Fig. 4 an internally. disposed chime 5c is employed, the same being welded at its upper edge to the edge of the barrel rim 2c and having its lower edge seated upon the internal shoulder 4. The .thickness of said chime is somewhat less than the extent of the offset. by which said shoulder is formed, thereby to cause said shoulder to also afford a seat for the barrel head 9?. Said chime has an annular channel 8c formed in its inner face designed forthe reception of a circumferential rib or extension 14c formed on convexly curved form, as shown vits flange disposed in parallelism a gasket 13 of com-y an expansion ring 12. As shown in said figure, the head flangellc is made of such height that, when the head is seated, its upper edge lies substantially flush with the shoulder afforded at the lower edge of said channel 8c to form with said shoulder a seat whereon may rest agasket 13c which is compressed by the overhanging rib 14c when said ring is expanded into interlocking relation with said chime.

Any suitable means may be employed for expanding and contracting the. expansion ring, the deviceherein shown being simply disclosed as an example of a simple, practicable and comparatively inexpensive form of means for effecting the desired adjustments. Such device comprises a turnbuckle 18 which has its opposite threaded ends adjustably-mounted in radially disposed lugs 19 formed on the inner face of the ring adjacent tothe ends of the latter.
